Disney Parks Inspired Cheshire Cat Tails

You can find this sweet treat over in Fantasyland in Magic Kingdom, and there's also is a version over in Animal Kingdom.

Start by heating 1 1/2 cups of milk and vanilla over medium heat. ⁠
Combine egg, additional egg yolk, sugar, and corn starch, in a bowl and whisk until fully combined and thick.
Once the milk has heated but not come to a boil, add about 2 tablespoons of the milk mixture to the egg mixture while whisking, once fully combined add 2 more tablespoons continuing to whisk. Then add the remainder of the milk into the eggs and whisk until fully combined. ⁠
Return mixture to stove and cook over medium heat for about 3- 5 minutes whisking constantly until the mixture is thick.⁠
Cover with plastic wrap and allow it to cool.

Defrost frozen puff pastry and roll it out until it about doubles in size. You are going to want to keep it shaped like a rectangle.
Spread the creme patisserie over the rolled-out dough so it is in an even thin layer.⁠
Sprinkle with mini chocolate chips, or more if that is your thing. ⁠
Fold the dough in half, along the short edge, sort of like a book. ⁠
Cut into 1 1/2 inch strips.
Place on a parchment-lined baking sheet, and twist a couple of times to give it that cattail look, combine beaten egg with a splash of water, and brush onto the top of each pastry. ⁠
Bake in a 400-degree oven for about 20 minutes or until golden brown.⁠

Combine powdered sugar, and about 1-4 Tbsp of milk, and whisk until combined. You want to start by adding 1 tablespoon of milk and gradually add more until it reaches the desired consistency. It should be thin enough to drizzle but should hold its shape for a couple of seconds when it falls into the bowl.⁠
Separate into 2 bowls and color with PINK and PURPLE food coloring, adding more powdered sugar if it becomes too thin. ⁠
Drizzle on icing with a spoon, going back and forth. ⁠
